目前使用官方的imx6qsabresd开发板，使用中发现官方BSP（Linux3.14.52）只支持echo 1 > /sys/class/graphics/fb0/rotate，垂直翻转，如果想实现180度水平旋转应该怎么做？
one can find the diff code in the link as below for reference, but this code is based on the 3.14.28, for your kenel maybe you need to change something, and if you want to rotate video, one can use gstreamer too
i.MX6 IPU and rotating a frame buffer
thanks for answering me,how can I use gstreamer to achieve the rotation,can you give me a example?
add the roation parameter in the command, for example:
gst-launch playbin2 uri=file:///video_file video-sink="mfw_isink disp-width=640 disp-height=480 rotation=3"
I used the command as you said above , it still didn't work.thanks for your patience.
